VALENTINE S. PERAZIO, OF NEW YORK, Y.

PIPE-COUPLING.

To all whom 'it may concern.'

Be it known that. l, VALENTINE S. PERA- zio, a subject of the King olitaly, and a resident otl the city ot' New York, borough o't Manhattan,in ihe county and State of New York, have invented a new and ImprovedPipe-Coupling, oi' which the i" llowing is a, full, clear, and exactdescription.

My invention relates to pipe couplings admitting ot general use, andmore part-icularly to pipe couplings of a kind carried by vehicles forthe purpose of conveyingliquid hydrocarbon fuel from one part of thevehicle to another.

More specifically stated, my invention eomprehends a pair of pipesections fitted accurately together, so as to prevent leakage whensecured together, and improved clampy ing mechanism, simple in designand etiicient in action, connected with the ends for securing themtogether and releasing them at will, this operation being performedinstantly and without the need ot' wrenches, thus lessening the risk oftwisting oil the ends of the pipe section, as well as' saving time androom.

Reference is to be had to the accompanying drawings forminff a part ofthis specilication, in 'which similar characters of reference indicatecorresponding parts in all the figures.

Figurel is a side elevation showing m improved pipe coupling complete,the en s of the pipe being connected Fig. 2 is a. lohgitudinal centralvcrt-ical section through the same; Fig. 3 is a side elevation of thesame parts appearing in Figs. l and 2, but` showing the clamping leveras moved Jfor the purpose of nncoupling; the lower part of this ligurealso showing in dotted lines the appearance oi the pipe sections whendisconnected; Fig. 4.` is a plan View of the mechanism shown in Fig. 1;and ll`ig. 5 is a scction on the line 5 5 of Fig. 1, looking .in thedirection of the arrow. s

At 6, 7 are two separate pipe sections, the' ipe section 7 beingprovided with an enarged portion 7m, and the pipe 'section 6 beingsimilarly provided with a. portion 8, of increased diameter. The pipesection 6 is further provided with a disk-like head 9, integral with theenlarged portion 8. A sleeve 10, encircles the disk-like head D andextends some little distance along the enlarged portion 9. The sleevel()` provided Specification of Letters Patent Application filed .Tanuary20, 1910.

with a throatl1, which the enlarged portion S.

At 1Q, is a void or space having a general annular form and of variahlelength, depending upon the position of the- Sleeve 10 relatively to theenlarged portion 8. A spiral spring .13. is mounted withinV the sleevev10 and rbears against the throat 11 on the one hand andl against Ythedisk-shaped head 9 on the other. The pressure of the spring 13 tendsnormally to force the sleeve 1() to the le'lt according to Fig. 2.

The head 9 is provided with a seat 1li, of a general concave form. Thesleeve 10 is provided with ears 15, and mounted Within the latter arepivot pins 1X6, a cam lever 17, being mounted upon these pivot pins andadapted to turn or rock within reasonable limits. The cam lever 17 hasgenerally a U- shape, being provided with a cui ved portion .17, whichis adapted to lit neatly against the adjacent side of the pipe section7. The cam lever, because of its shape, can thus lie in very closeproximity to the pipe section 7, beingl thus very compact and for somepurposes practically concealed. The cam lever 17 is provided with twolobes 18, serv- .ts neatly around ing thc purpose of cams. The pipesection 7 provided with a disk-like head 7", integral with the enlargedportion 71 and provided with' a convex surface 7c, mating the concaveseat 14 and adapted to fit the same accurately, so as to form a tightjoint.

The operation of my device is as follows: S0 long as the two pipesections remain disconnected, the tension of the s ring 13, by pressingthe sleeve l0 to the le t, according to Fig. 2, causes a portion of thehead 9 to lbe exposed, as will be understood from Fig.

3. Suppose, new, that it be desired to couple up the pipe sections. Theconvex portlon 7c of the pipe section 7 .is titledI neatly into the seat14, the outer portion of the head 7b being thus brought. into engagementwith the outer portion of the head 9. lVhile this takes place, the camlever 17 is raised-that is, occupies the position indicated vin Fig. 3.The cam lever is now grasped by the operator and lowered-that is,pressed into the positions indicated in Figs. l, 2 and 4, se that theportimi 7u of the cam lever lodgesI against and partially encirclcs thepipe section 7. By this movement of the cam lever', the lobes 18 pressthe head 7" to the lett according to the figures just mentioned andagainst the head 9, the convex portion 7 being thus caused to bind hardagainst its seat 14. This causes the head 9 and portion 8 of the pipesection 6 to move to the left, according to Fig. 2-or, what amounts tothe same thing, causes thevsleeve 10 to be drawn to the right so as topartially overlap the joint between the heads 7b and 9.

The sealing of this joint is thus perfected in case the convex portion 7c, in binding against its seat 14;, fails to make a perfectly tightjoint. In order to uncouple, the operator grasps the cam lever `17 andraises it into the position indicated in Fig. 3. The pipe section 7 isnow moved axially in relation to the pipe section 6-that is, the head A7 b is slipped laterally 0E the head 9 and the pipe sections are thusuncoupled.

While I show all'parts of each pipe section as integral therewith, I donot limit myself to this exact form for the pipe sections-or either ofthem.

Having thus described my invention, I`

claim as new and desire to secure by Letters Patent:

l. In a pipe coupling, the combination of a pipe section provided with ahead having a concave seat, a second pipe section pro vided with a headhaving a convex portion a'elaaio for fitting against said seat, a sleevemounted upon one of said pipe sections and movable relatively to thesame, said sleeve being movable for the purpose of enabling it to coverthe joint between said heads, a spring for normally retracting saidsleeve so as to uncover said joint, and cam mechanism for' forcing saidsleeve against said spring,

4thereby compressing the same and moving said sleeve over said joint.
